Maximum measuring

error

IFC 050: 0.5% of the measured value above 0.5 m/s,

below 0.5 m/s, deviation ± 2.5 mm/s

DN25...300; IFC 100: down to 0.3% of the measured value ± 0.5 mm/s

DN25...300; IFC 300: down to 0.2% of the measured value ± 0.5 mm/s

DN350...600; IFC 100: down to 0.5% of the measured value ± 1 mm/s

DN350...600; IFC 300: down to 0.4% of the measured value ± 1 mm/s

The maximum measuring error depends on the installation conditions.
